- the SASL authorization callback
cc [ flag ... ] file ... -lsasl [ library ... ] #include <sasl/sasl.h> int sasl_authorize_t(sasl_conn_t *conn, const char *requested_user, unsigned alen, const char* auth_identity, unsigned rlen, const char *def_realm, unsigned urlen, struct propctx *propctx);
sasl_authorize_t() is a typedef function prototype that defines the interface associated with the SASL_CB_PROXY_POLICY callback.
Use the sasl_authorize_t() interface to check whether the authorized user auth_identity can act as the user requested_user. For example, the user root may want to authenticate with root's credentials but as the user tmartin, with all of tmartin's rights, not root's. A server application should be very careful when it determines which users may proxy as other users.
The SASL connection context.
The identity or username to authorize. requested_user is null-terminated.
The length of requested_user.
The identity associated with the secret. auth_identity is null-terminated.
The length of auth_identity.
The default user realm as passed to sasl_server_new(3SASL).
The length of the default realm
Like other SASL callback functions, sasl_authorize_t() returns an integer that corresponds to a SASL error code. See <sasl.h> for a complete list of SASL error codes.
